May 1, 2026

May 2026 monthly summary: Delivered OLMv1-ready Tempo operator bundle for Konflux Tempo with a 4.21+ end-to-end testing pipeline and static validation, strengthening production readiness on OpenShift 4.21+. Implemented bundle-sdk validation and in-tree OLMv1 checks to catch issues early and reduce deployment risk. Completed a 4-21 e2e pipeline wired to FBC snapshots, enabling consistent testing against the latest feature branches. Also upgraded Grafana Tempo operator to Tempo 2.10.5 and refreshed observatorium/api gateway, bringing a security patch (CVE-2026-28377) and new endpoints; no operator-side config changes required. Improved image reference handling by stripping tags to ensure digest-only references for skopeo copies. Overall impact: higher deployment reliability, faster risk mitigation, broader supported scenarios, and stronger security posture. Technologies/skills demonstrated: OLMv1, operator-sdk, Tekton pipelines, OpenShift 4.21+, FBC snapshots, scripting (Python/Bash), Go, and gateway/API collaboration.
